Diagnosis: Male with epandrium and surstyli oval (posterior view) ( Fig. 5J ). Lateral surstylus shorter than epandrium; posterior lobe of surstylus broad, not longer than anterior lobe ( Fig. 3J ). Proctiger quadrate and smaller than epandrium ( Fig. 3J ). Medial surstylus longer than lateral surstylus tapering towards apex with a pair of thick prensisetae ( Fig. 5J ). Phallus 2.5̄ 2.8 mm long, excluding glans (0.43 mm); 0.75 of glans sclerotised with unpatterned praeputium; subapical lobe and basal lobe present ( Fig. 8J ). Female with brown, dorsoventrally flattened oviscape (1.01 mm); eversible membrane (1.45 mm) with spicules on distal end semicircular without any pointed projections ( Fig. 11G ); aculeus 1.4 mm long, tip trilobed with 4 pairs of preapical setae ( Fig. 13G ); two black, tightly coiled mulberry shaped spemathecae ( Fig. 15G ).
